ROTARY STEAM-ENGINE.

Specicati t ters Patent. Patented Feb. 27, 1917s Application medFebruary 24, 1916. serial No. 80,218.

To all /whom 'it may concern:

Be it, known that I, JOSEPH H. JACKSON, a citizen of the United States,residing at Birmingham, in the county of Jefferson and State of Alabama,have invented a new and useful Rotary Steam-Engine, of which thefollowing is a specification.

The present. invention appertains to steam or pressure Huid engines, andaims to provide a novel and improved rotary engine using steam or othermotive Huid.

With the foregoingl and other objects in view which-'will appear as thedescription roceeds, the invention resides in the comination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment ofy the invention herein disclosed can be made within thescope of what is claimed without departing from the spirit of theinvention.

The invention is illustrated in the accompanying drawings, Whereinz-Figure 1 is a side elevatlo'n of the improved engine. i

Fig. 2 1s a reduced vertical section thereof taken on the line 2-2 ofFig. 3, portions being shown in elevation and portions being brokenaway. j

Fig. 3 is another vertical section taken on the line 3 3 of Fig. 2,portions being shown l in elevation. p

4 The engine is carried by a suitable base or frame 1 having thepedestals 2.and 3 provided at their upper ends with the respectivebearings 4 and 5, and a' wheel or disk 6 d isposed adjacent the innerside of the pedestal 2 lhas a central shaft. or spindle 7 attacliedthereto and journaled through the bearing 4. The disk 6 is prvided atthat face remote from the pedestal 2 with an out'- standing rim 8defining a square opening orA recess 9 and theinwardly facing Ichordalplane faces 10. The disk 6 acts as a liy wheel when the engine is inoperation.

Mounted for rotation within the bearing 5 is a tubular member 11disposed eccentriw cally relative to or above the shaft 7. The tubularmember 11 is provided with a diametrical longitudinal partition 12extending from .the innerA end to a point outside of the pedestal 3.,and said partition provides' I the passages 13 and 14. The tubularmember 11 has an outstanding nipple 15 communicating with the outer endof `the passage 14. The steam or pressure fluid 1s supplied by way ofone of 'said passages, say for example, the passage 13, and the steam iseX- hausted through the other passage14. The tubular member 11 isprovided adjacent its inner end which projects from the bearing 5 towardthe bearing 4, with openings 16 and 17 communicating with the respectivepassages 13 and 14.

Mounted f orrotation upon the inner protruding port1on of the tubularmember 11 is a roton 18, and 'said rotor or drum 18 has a centralsocket. or recess 19 receiving the( The rotor 18 has ayplurality, inthis case four.

inner end portion of the member 11.

radial cylinders 21 and reduced ports 22 eX- tendmg from the inner endsof the cylinders to the socket 19 and adapted to move into` and-out ofregistration with the openings 16 and 17 of the Huid controlling member11.

. A piston 23 is slidable within each cylinder '21A and is provided with-one or more packing rings to prevent leakage, andthe pistons haveoutstanding piston rods or stems 2,4 attached at their outer ends toshoes 25 bearing slidably 'against the faces 10.

The rotor 18 is preferably provided with packing means 26- surroundingthe mouth of the socket 19 and embracing the member 11 to preventleakage, and a 'radial handle 27 is attached to the member 11 tofacilitate the rotationof said -member for purpose of reversing theoperation ofthe engine.

The opposite shoes and their pistons are coupled together'by yokes, eachof which embodies a pair of parallel'bar's 28 which have their remoteends secured,l as at 29, to thev outer edges of the opposite vshoes'25.The

two pairs of bars 28 cross 'each other, and theA bars 28 of each pairare disposed at the opposite sides-of the member 11. rllhe outer side ofthe.rotor 18 has outstanding bosses a 30 between the bars 28, to assistin guiding said bars, and plates 31 are bolted or otherwise secured tothe bosses 39 vand overlap the bars 28 to hold them in place adjacentthe 'outer side of the rotor.

A their lowest point, their ports 22 after hav',-` ing left the opening16,- will be brought into registration with the opening 17, and saidwhich-are in registration with saidlopening 16, and will therefore flowinto the corresponding cylinders 21 to force the respective pistonsoutwardly. The member 1ll isjso set, as seenin Fig. 2, that when thepistons reach their highest point, their ports 22 come into registration'with the opening 16, and as the cylinders move downwardly at the leftyhan'd s'ide of Fig. -2, theports 22 remain in registration with saidopening 16, so' that steam will flow into" thejdownwardly movingcylinders. As the cylinders reach ports will remain in registration withthe opening 17 during the upward movement of Lthe cylinders at the righthand sideof Fig.

2. Due rto the eccentric arrangement of the disk 6 and rotor 18,the'face 10 at the top will be closer to the center of the rotor thanthe lowermost facelO, and as the rotor and.

dueto the sliding 'bearing of the shoes 25 against the faces 10, therotor will be rotated with the disk 6. As the shoes move upwardly theyare forced inwardly toward the rotor, thereby forcing the correspondinpistons inwardly, to eject the pressure fluid through the passage 14.The shoes 25 slide relative to the faces 10 as the parts rotate, and theopposite shoes being yoked together will operate in unison.

'is claimed' as new is:

slightly i-,eimee To reverse the engine, the tubular member 11'is-rotated through an arc of 180 degrees,

which reverses the flow of duid" into and out' of the cylinders, so thatnaturally the rotation of the engine is reversed.

Having thus described the invention, what A f Huid pressure engineycomprising a frame having a p'air of eccentric bearings, a

shaft journaled in one bearing, a wheel adjacent the inner side of saidbearing secured to said shaft and having an outstanding. rim `projectingaway from said bearing vand providing inwardly facing chordal faces, atubular member extending through? and having a pair of pasthe otherbearing sages and openings communicating there with, la rotor having acentral socket receivu ing said tubular member, said rotor having radialcylinders and portsat the inner ends of said. cylinders to register withthe aforesaid openings, the inner side of said rotor having a bossbearing against the wheel, pisitons working within the cylinders andhaving outstanding rods, shoes attached to the outer ends of said rodsand bearing against said faces, crossed slotted yokes terminallyattached, to the opposite shoes and located at that side of the rotoropposite said wheel,

' said'tuloular member extending through the lslots of said yokes, thatside ofthe rotor remote from said wheel having outstanding bosses'within the slots of said yokes, and plates secured to the last mentionedbosses and overlapping the yokes to hold them in place adjacent to therotor.
